Everytime my friend checks-in on Facebook I get a notification on my iPhone… how do I stop this?

I’m not tagged in the places they are checking into or anything. I don’t get notifications of any other friend’s check-ins… only this 1 person. How do I stop this? Its really annoying to get these notifications when I didn’t set them up and couldn’t care less where they are checking into
